FIGS. 1 to 5 b illustrate the head assemblies of a putter according tothe preferred embodiments of the present invention applied to variouslyconfigured and shaped putters.

A putter P1, to which the head assembly according to the preferredembodiments of the present invention is applied, is made of a solidplate or a hollow plate extending from the central portion of an uppersurface 10 of a head H1, to which a shaft S is installed, to the rearside of the upper surface 10 of the head H1, and is preferablyintegrally formed with a guide plate 20 having an integrated gaze guide21 formed on the plate and having various shapes. However, the headassembly according to the preferred embodiments of the present inventioncan be applied to the putter P1 as shown in the drawings and to anyputter regardless of kind and shape.

The guide plate 20 includes the gaze guide 21 having a guide line 22, asshown in the drawings, formed in the upper surface of the gaze guide 21,such that a golfer gazes when impacting a golf ball (not shown) with theputter. However, the gaze guide 21 is not always provided to the putterP1 of the present invention.

A bolthole 23 is formed at the rear lower side P of the guide plate 20integrally formed with the head H1. The bolthole 23 is not a penetratinghole, but is a closed bolthole starting from the lower side of the guideplate 20 and ending at the intermediate portion in the thicknessdirection of the guide plate 20.

Metal disc weights, which are determined by experimentation, havevarious weights, and have various shapes, i.e. disc weights 30, 30′, and30″, as shown in the drawings, are integrally formed with fixing shafts31, 31′, and 31″, respectively, and the fixing shafts 31, 31′, and 31″respectively have threads 32, 32′, and 32″ formed in the end portionsand inserted into the bolt hole 23.
